Answer is 4

x^3 = 64

this means a number to the third power is equal to 64. in other words, a number multiplied by itself 3 times equals 64

x= cube root of 64

64 is a perfect cube, which are best to memorize. 4 x 4 x 4 = 64 so x = 4

You and a friend are going camping for the night and you both bring camping stoves. Your stove is 25 percent efficient, and uses

lesya692 [45]

Answer- 0.05 lit of propane fuel will your friend need in order to boil 10 cups of water.

Solution-

The more efficient the stove is ,less the fuel you need to burn.

so efficiency and amount of fuel needed are inversely proportional with each other.

Given

Your stove is 25 percent = 0.25 efficient ,will boil 10 cups of water, using 0.1 lit of fuel .

0.25 × 2 = 0.5 =50 percent efficient stove ,will boil 10 cups of water, using 0.1/2 = 0.05 lit of fuel.

(∵ As multipling a factor of 2 with efficiency will make the amount of fuel needed half.)

You want to ship textbooks from Florida. The textbooks are $60 each plus $150 shipping. Let x represent the number of textbooks

sertanlavr [38]

I am assuming the problem is asking you to find an equation repersenting the situation.

In this case, realize that 150 will be a constant, and 60 will be attached to the $x$ variable, since the price of the textbooks changes based on how many textbooks there are.
